Power Query not recognising simple date type

Hi All,

I have a data set with a frustrating issue where some dates are throwing errors :

 

 

DataFormat.Error: We couldn't parse the input provided as a Date value.

 

 

I have checked there are no rogue spaces or characters in the data set and are indeed consistent d/mm/yyyy throughout the column.

 

What is even weirder is that when i create a separate powerBi file and query the same table with the EXACT same M code, there are no errors, and the column recognises the dates.

 

Original Error:

Separate new blank PBI, Exact same M code copied and pasted into advanced editor... no errors:

What could be causing this issue??

@awff , if you system is having US date format, then it might give issue with UK date format

of do conversion

DD/MM/YYYY to MM/DD/YYYY
date(year( right(DD__MM__YY[date],4)), month(mid(DD__MM__YY[date],4,2)) ,day(left(DD__MM__YY[date],2)))
